Use of GIS technology in flood risk analysis. Case study Mila 23 locality from the Danube Delta

Abstract

Floods are phenomena that occur quite often in the deltaic space, with an increased impact on the environment, localities on the water course, human health and economic activity. This paper presents flood risk analysis using GIS specialization programs for a vulnerable area in the Danube Delta. The target area of this study is shown in Figure 1. The results show the areas where water can reach quickly in the event of heavy precipitations from rains or behind the protection dam failure caused by a strong flash flood. The results are presented as digital maps processed in GIS software that shows the vulnerable flood areas in Mila 23 locality. The general information base used in the processing of all data is the digital terrain model with a meaningful content of land configuration information. Flood risk is a subject of great concern to researchers, in recent decades the Danube Delta has been beset by numerous natural hazards, of these the floods are the ones that most often manifest.
